Definitions
- the present invention relates to a ship unloading mechanism having an endless compartmented belt conveyor operating in the vertical direction and with the aid of which material to be lifted is transported from a ship's hold at the lower end of the conveyor onto a horizontal conveyor at the top end of the conveyor, the material being thence further transported e.g. onto a quayside conveyor.
- the present invention provides a ship unloading mechanism, comprising an endless, vertically operating compartmented belt conveyor for transporting material to be lifted up from a ship's hold, said compartmented belt conveyor having upwardly facing compartments for receiving said material, a horizontal conveyor at a top end of said compartmented belt conveyor for receiving said material and for further transporting said material, and means at a lower end of said compartmented belt conveyor for supplying said material to said compartmented belt conveyor, said supplying means comprising vaned wheel means for flinging said material at high velocity from the hold into said upwardly turning compartments of said compartmented belt conveyor.
- the present unloading mechanism can operate extremely fast and efficiently because high speed belt conveyors can be employed when the material is supplied in the belt's direction of travel, that is, the belt is not required any more to "tamp" the material in the transporting direction, instead of which the velocity imparted by the vaned wheel means to the material, and its direction, are consistent with the speed and direction of advance of the belt.
- screw conveyors are provided at opposite sides of the vaned wheel means, on a common shaft, which detach the material in the ship's hold and transport the material to the vaned wheel means.
- the material can thus be collected for transport to the vaned wheel means from a very broad area, and from the vaned wheel means it will further fly onto the compartmented belt conveyor.
- An upwardly transporting half part of the compartmented belt conveyor is, e.g. with the aid of rollers, forced to assume an outwardly curving configuration equivalent to the belt's dip at its maximum negative unloading angle, and a cover sheet belonging to the compartmented belt is similarly curvilinearly shaped and immediately adjacent to the compartmented belt.
- the upwardly transporting part of the compartmented belt is enabled to travel along a given curve and it is not compelled to rub against the cover sheet when the unloading angle is negative.
- the upwardly transporting part of the compartmented belt is located below the part of the compartmented belt which is running downwards. Since the belt conveyor is preferably made of rubber, even unloading of difficult materials becomes possible.
- FIG. 1 shows a ship unloading mechanism according to the present invention and a crane
- FIG. 2 shows the lower end of the unloading mechanism in vertical section
- FIG. 3 shows the lower end of the unloading mechanism in front view and partly broken away in section
- FIG. 4 shows the compartmented belt conveyor of the unloading mechanism at a so-called negative unloading angle
- FIG. 5 shows a section along the line V--V of FIG. 4.
- FIG. 6 shows a part of the compartmented belt.
- the unloading mechanism indicated generally by reference numeral 1 comprises an endless, vertically operating compartmented belt conveyor 2, by the aid of which material to be lifted will be transported from a ship's hold (not shown) onto a horizontal conveyor 3 located at the top end of the compartmented belt conveyor 2, whence the material is further transported to a quayside conveyor 4, etc.
- a material supplying means comprising a vaned wheel 6, the vanes of which fling the material at high velocity, in the direction indicated by an arrow 7, into upwardly turned compartments 8 of the compartmented belt conveyor 2.
- a cover sheet 12 belonging to the compartmented belt conveyor 2 is in corresponding manner curvilinearly shaped and immediately adjacent the compartments of the belt. Therefore, the material will travel enclosed in these compartments, whatever the angle at which the compartmented belt conveyor is positioned.
